PILING MACHINE.

application med april 17, 1922. seran` No. 553,706.

This invention relates to a stack-ing or piling machine and a method in which -a sliver of fiber or the like material is piled 1n a symmetrical form. It is particularly adapted as an 'attachment' for a slivermg machine which is used in connection with the manufacture of binder twine, rope 'or other like fibrous material. "r The objects of this invention are to provide a method and meansl for piling or stacking the sliver in a series of overlapping loops as it is fed from the sliver'ing machine without the liability of twisting or tangling the sliver of fiber.

A further object is to provide a simple and`- economical construction and one in which the rvarious mechanisms cooperate in a manner to produce a stable stack or pile.

These and otherv objects are attained by providing an attachment for a sliverng or the like machine comprising an. oscillating chute through which the sliver is fed, `positioned over and to one side of the center. of a rotating table for piling thematerial in a symmetrical and stable pile.

Referring to the drawings- Fig. 1 is aside elevational view showing part of a slivering machine having our improved piling attachment embodied therein; Fig. ,2. isa front elevational view .of the piling machine shown in Fig. 1; Fig. 3 is an enlarged top plan view of the rotating vtable 4showing diagrammatically the position of the sliver as it is delivered in overlapping loops 'to form a pile; k Fig. 4 is a detail cross' sectional' view of the worm and gear driving mechanism for rotating the table;

Figs. 5 and 6 are top pla-n and side elevational views respectively of the eccentric drive for the oscillating chute; and Y Fig. 7 is anI enlar ed ldetail view of the gears that drive the eed rollers.

For the purposes of illustration we have shown oui-'improved piling attachment connected to a slivering machine comprising a -main frame 10, only part of which is shown, v `and main rollers 11 mounted in the bearing brackets 12. Main rollers 11 are operatively driven Yby the power pulley 13. Securely fixed to the main frame 10 are upwardly inclined elevator' frame members 14 positioned on the opposite sides of the machine in a manner to form bearing supports for. the endless elevator rollers 15, 16, 17, 18 and 19. Surrounding the rollers 16, 17, and 19 is an endless elevator' belt 20 ,which is normally held ktaut by the adjustable member 21 l which in turn is connected to the adjustable bearing of the roller 17, (not shown). The roller 16 .is operatively driven by being geared to the lower roller 11, (not shown). 'lhe rollers 15 and18 are connected to an endless elevator belt 22 adapted t0 .operatively contact with the endless elevator belt 20 in a manner to cooperate in the elevation of the sliver as it is delivered to the piling machine. The above describedv mechanism per se vdoes not form any part of the present invention and it is therefore thought that a more detailed description of the same is not necessary.

Laterally extending from and integrall with the elevator frame members'l; are the arms 23.. These arms 23 are provided with 'bearing apertures adapted to receive the these two shafts. The shaft 24^operatively drives the shaft 25 by means of a gear 24 v'engaging a similar gear 25- ixed respectively to the shafts 24 and V25, (see Fig. 7 Positioned above the rollers 27 and 28 is a funnel-like chute 29 held in position by a cross bar 30 fixed to the elevator frame mem-Y bers 14 by means of brackets 31.` The funsv nel-like chute 29 is positioned with its 1a r mouth 32 to receive the sliver as it is eliveredv between the v elevator eonveyersv 20 and 22 at the ,rollers 18 and 19. Positioned below the rollers 27 and 28 is an oscillating chute 33 pivoted at 34 to laterally extending brackets 35 which are fixed to across bar 36 secured to the elevator frame members 14.

ioo

The means for driving this oscillating sliver l delivering chute 33 comprises a yoke mem-A ber 37 pivotally secured to the chute 33 by means of studs 38 and bolts 39. The yoke 37 is adjustably connected by a bolt 40 to a transverse bar 41. The bar 41 is connected at its opposite ends to rings 42 ywhich are rotatably mounted on eccentric disks 43 xed to a shaft 44, (see Figs. 5 and 6). The shaft 44 is journaled in the bushings 45 mounted in the elevator frames 14. The shaft 44 is operatively driven by the gearing mechanism 46 connected to the shaft 19 of the roller 19 as shown in Figs. 1 and 2. Diagonally disposed with respect to the oscillating movement of the chute 33 is a guidingy member 47 fixed to an extending arm 48 which in turn is secured by means of bolts 49 tol the elevator frame 14, (see Fig. 3). The guiding member 47 is adapted to guide the sliver of fiber as the sliver is delivered from the oscillating chute 33.

In connection with our improved piling machine, we have provided a rotatable table 50, the center of which is positioned belowT and to one side of the oscillating chute 33. This rotating table 50 is preferably made of steel and securely mounted on a webbedspindle 51 journaled in a supporting bracket 52. The bracket 52 is secured by means of bolts to the channel members 53 which in turn are supported by the angular members 54 secured to the floor beams 55. .The spindle 51 is provided with a vertically extending shaft 56 which has secured thereto a gear 57. The lower end Aof the shaft 56 is supported in a bearing bracket 58 secured to the bracket 52 by means of bolts 59. The rotating table 50 is operatively driven through the shaft 60 pivotally mounted in a bearing 61 formed integrally with the bracket 52. The shaft 60 has securely fixed adjacent the bearing 6l a worm 62 adapted to mesh with the gear 57 to operatively drive they Same. The other end of the shaft 60 is provided with a sprocket 63 which is geared by means of a chain 64 to asprocket 65 fixed to the shaft 44. VFrom the construction above described, it

will be seenthat as the shaft 44 actuatesthe chute 33 in a back and forth direction, the gear 65 and chain 64 through the sprocket 63, shaft 6() and worm 62 will rotate the table 50. By reason of this simultaneous oscillation of the chute and rotation of the table,

the sliver is delivered in the form of loops in the manner shown diagrammatically in Fig. 3.

Additional means has been provided which cooperates with the above described mechanism to assist in forming the sliver of fiber in a symmetrical and stable pile. This means comprises a substantially circular shield 66 secured to the floor 67 adjacent-to and extending 180 degrees of the periphery of the rotating table 50. The shield 66 is secured to the floor 67 by means of the angle member 68. l The braces 69 are provided at intervals to reinforce and Support the shield 66.

It will be noted that the shield 66 does not entirely surround the rotating table- 50 but that an opening equal to the diameter of the rotating table 50 is provided to permit the withdrawal of the librous material after the same has been piled into symmetrical form. I

In the operation of the above described mechanism, the sliver of fiber, after passing -through the slivering machine, is fed to and passes between the rollers 11. From there it is conveyed between the elevating conveyers 20 and 22 upwardly. to and between the rollers 18 and 19 from where it is delivered into the funnel shaped chute 29. From this point it is fed between the feed rollers 27 and 28 downwardly through the ner to throw or loop the sliver outwardly toward the circumference or periphery of the rotating table 50 and, at the same time, the shield 66 confines the outward throw or loop of the sliver within the periphery of the rotating table. It will be seen from this construction that the combination of the rotating table, oscillating chute, guiding member 4and shield produces a stack of fibrous material in the shape of a series of overlapping elliptical loops in such a manner as to form a symmetrical and stablepile. As vthe sliver pile assumes substantially the height ofn the shield 66 the pile is removed by the operator or attendant with a large hook and a new pile is begun on 4the bottom of the table in the manner above described.
